THE NUMBERS, EXPLAINED
How to use this calculator.
Same-day handover at the care location. Incoming arrival is departure plus travel; negative overlap indicates an uncovered gap.
Start with your inputs
Enter outgoing carer shift end (minute of day), incoming carer departure (minute of day), incoming travel duration (min), required handover overlap (min). Keep amounts in the units shown on each field. The example is a starting point, not a recommended value.
| Input | Example value |
|---|---|
| Outgoing carer shift end (minute of day) | 1020 |
| Incoming carer departure (minute of day) | 990 |
| Incoming travel duration (min) | 20 |
| Required handover overlap (min) | 15 |
A worked example
With the example inputs above, incoming arrival (minute of day) is 1,010. Change the inputs to explore your own scenario.
| Result | Example answer |
|---|---|
| Incoming arrival (minute of day) | 1,010 |
| Actual overlap (min) | 10 |
| Additional coverage needed (min) | 5 |
How this is calculated
Incoming arrival (minute of day)
Add travel time to incoming departure.
Actual overlap (min)
Subtract incoming arrival from outgoing shift end.
Additional coverage needed (min)
Subtract actual overlap from required handover time.
Symbols and units
- a
- Outgoing carer shift end (minute of day)
- b
- Incoming carer departure (minute of day)
- c
- Incoming travel duration (min)
- d
- Required handover overlap (min)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions and limits
Same-day handover at the care location. Incoming arrival is departure plus travel; negative overlap indicates an uncovered gap.
Calculations use the values you enter. Blank or invalid inputs show an error instead of silently substituting zero. Results are displayed to useful precision; calculations retain the underlying numeric precision.
Questions about this tool
What does the result tell me?
Incoming arrival (minute of day); Actual overlap (min); Additional coverage needed (min). The result applies to the method and inputs described above. Check the units and assumptions before using it in a decision.
Why might another calculator differ?
Differences in units, rounding, timing or model definitions can produce different answers. Compare the input definitions and the method, rather than only the final number. For this tool: Same-day handover at the care location. Incoming arrival is departure plus travel; negative overlap indicates an uncovered gap.
